PATENT GFFICE ROBERT BRIGGS AND FLOYD COLE, OF .PHARR, TEXAS WI RE CUTTING AND TWISTING DEVICE :App1i cation filed January 28, 1933. Serial No. 654,039.

This invention relates'to wire cutting and twisting machines or devices. a

An object of this invention is to provide a manually operable wire cutter and twisting means which is so constructed as to clampthe strands of wire within the; device at the same time the strands are cut so as to permit the twisting of the device and strands of wire together. a 7

Another object of this invention is to provide a device ofthis kind which is so con-' structed that it can be usedsubstantiallyas acrank or turning means to rotate the device about the wire strands while holding the ends of the strands together and thereby twisting the strands one about the-others .The above and various other objectsand advantages of this invention will in partbe described and-in part be understood from the following detailed description" of the present preferred embodiment, the same being illustrated in the accompanying drawing' wherein 1 Figure 1 is a longitudinal section partly in detail of a device constructed according" to the preferred embodiment of inven'-' tion. I

Figure 2 is a fragmentary-frontelevation ofthe device.

Referring to the numerals of reference" designate corresponding parts and this block 11 has'a pair of arms 12 integral therewith extending outwardly of one end of the handle and extending at substantially a right angle to the longitudinal axis of the handle 1 0 and laterally thereof. A curvedtubular member 14 hav 7 ing a bushing or sleeve 15 secured thereto is rotatably mounted within-thehandle 10 and is held against longitudinal movement in at least one direction by means of a cap 16, which is threaded onto the opposite end of the handle 10. 1 r.

Ball bearings or anti-friction elements 17 are interposed between the cap 16 'and the' outer end of the bushing 15, so that the drawing wherein like throughout the several views, the

numeral 10 designates generally a tubular- V handle of desired length, which has securedr thereto a block 11 as by a'pin or screw 13;

' has one end handle 10 may be rotated relative to the curved tubular member 14. A substantially U-shaped fixed jaw 18 is formed-with the tubular body member 14, and this jaw 18 has an opening 19 to receive strands of wire. The jaw 18 has a cutter 20 on one side of the opening. 19, and a movable or rockingjaw 21 is mounted on a pivot 22earried by'the fixed jaw or head 18 and is swingable across the opening 19, and is adapted to coact with the fixed cutter 20 in shearing or cutting the strands of wire positioned in the jaw opening 19.

A 'movable jaw operating means, generally designated as 23, is connected at one end as by a connector 24 to the movable jaw 21, and this jaw operating means 23 includes a plurality of spherical members 25 in the form of balls, which are mounted within the tubular member 14.

A plunger 26 is slidably mounted at one end inthe inner end of the tubular member 14 and-abuts against. the innermost of the spherical members 25. The opposite end of the plunger extends through the bearing block 11, and is provided with a head 27 abutting against the curved portion 28 of a pivotedlever29 carried by the arms 12.

An expanding spring 80 engages at one end against a seat 31 formed in the bearing block 11', and the opposite end of the spring engages against the head 27 so as to constantly maintain this head 27 in-contact with thecurved portion. 28 of the lever 29. A lug 32 is carried by the lever 29 at the pivoted end thereof,and is adapted. to engage against a stop pin 33, which'limits the rocking of the lever 29 in open or inoperative position;

The movable jaw. 21 confronts a clamping jaw '34mounted on-a pivot 35. The clamping jaw 34 has the inner or free end thereof disposed inv contacting relation with a cutout portion 36 in the lower or movable clamping jaw 21. A spring 37 engages at one end against the clamping jaw 34 and at the opposite end against a flange 38 formed withthe fixed jaw member 18. A threaded stop 39 extends through the spring 37 and thereof disposed adjacent the jaw member 34 and limitsthe rocking movement of this jaw member 34 under the pressure applied by the movable jaw 21.

A spring 40 is secured at one end to the free end of the movable jaw 21 and at the oppositeend, as at 41, to the tubular body member 14:. This spring 40 acts to constantly urge the'movable jaw 21 into Open position and to maintain the member 24 into contact with the balls 25 so that these balls 25 "will be held into contacting relation w1th each other at all times. j

In the use and operation'of this device, the wire strands are passed through the jaw opening 19 with the movable jaw 21 in released position. The lever 29, is then rocked toward thehandle 10, which action forces the plunger26 inwardlysof the handleand movesthe .jaw 21 into'shearing positionrel-v ative to the; cutter 20 so that the strands of wire positioned within the opening 19 will be cutby the movable cutting jaw 21, which operates as a shears to cut oil the strands of wire.* At thesame time the movable jaw,

21 .coacts with the fixed jaw 20 to shear the wire, the severed strand'slof wirewill be clamped between thejaws21 and 34. These strands will be held in parallel relation'ito each otherand with the 'wire strand'shs a pivot, the handle 10 including the lever 129} V is swung lnacircular movement about the Wirestrands, thereby twisting'these strands together and tightening the wir uponia;

package, boXor the like'. ,Due. to the rot-at able mounting of'the handlelO, the device can be readily rotated with the curved extension 14 acting as a lever to twist-the wire strands together which; are clamped 'between the two jaws 21 and 34. l i

It will be apparent from the foregolng that one of the strands of wire may be posi-' Vtioned with the end thereof substantially abutting against the inner, face of the-cutter path about the wirestrands.

20 while the otherstrand which may be connected to a roll or spool of wire may be passed entirely through the jaw opening 19.

Theiextension 14 constitutes a fixed part of the handle and acts tooffset the handlelO from the fixed jaw so that the desired pre'ssure or leverage can be applied to the twisting of the wire. V l "It Will be apparent, therefore, that there will be. no loss of wire dueito the cutting of:

the wire either before or after it-has been twisted upon-the package, and that the origi nal tension applied to the: wire inithe wrappingthereof canbe increased bythe tension applied under the twisting action as, the:

handle 10 is swung or moved in a circular It is, of course, understood thatvarious changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted the following claims.
